#19 Centralize shared code in submission approval scripts

[Ahasuerus]

All "%a_*" scripts in the mod directory start with the following code:

PrintPreMod('Award Update - SQL Statements')
PrintNavBar()

try:
    submission = sys.argv[1]
except:
    print '<div id="ErrorBox">'
    print '<h3>Error: Bad argument</h3>'
    print '</div>'
    PrintPostMod()
    sys.exit(0)

    if NotApprovable(submission):
            sys.exit(0)

We should be able to move this code to PrintPreMod and reduce code duplication.
